Statistics list 4 to 39% of men have premature ejaculation. Treatment is usually with SSRI’s and Sildenafil (Viagra™). The disorder may be lifelong or acquired, global or situational, with different treatments. Discussion included the criteria for clinical trials. Objective assessment is made by number of thrusts and intra-vaginal latency time, but there is no information regarding a normal range of number of thrusts, and the average intercourse lasts 4-7 minutes according to current literature.
The classic definition of rapid ejaculation is if the man ejaculates within 1 minute of penetration. It is theorized that the central regulation is by dopamine and penile hypersensitivity, so treatment may be with Sildenafil and local anesthetic. If you have premature ejaculation there is a 91 % chance that a first degree relative (father, brother, son) will also have it. SSRI’s which are used for depression are a first line treatment as well. They may be used before intercourse or taken every night.
This treatment works better for people whose rapid ejaculation is acquired. Since Sildenafil is more effective than SSRI’s, a combination of an anti-depressant, local anesthetic and Sildenafil is effective in 97% of the time. The anti-depressant with sildenafil is signficantly better than the SSRI alone. Although this is currently the preferred therapy, medical insurance typically covers 30 pills for SSRI’s and only 4 sildenafil tablets per month. If that doesn’t work a local anesthetic like Emla cream (with a condom to protect the partner) should be added to the regimen.

This perspective article highlights the positive role of sildenafil in the management of PE (even without ED) with acceptable adverse events. Now that we have a standardised definition of PE from International Society of Sexual Medicine (ISSM) and a psychogenic component in PE definition, more randomised placebo-controlled studies are required to further establish its role.

If that still is not effective the patient make you intracavernosal injection. Fast acting SSRI’s specifically for rapid ejaculation are currently in development. Delayed ejaculation carries with it issues of inability to achieve orgasm and infertility. Anti-depressants or agents which act centrally such as Valium, anti-hypertensives and alchohol abuse all can affect this. First it is important to evaluate if this is a psychological problem, but a physical assessment must be made as well.
A common cause is pudendal neuropathy, caused by a crush to the perineum such as from bike riding with a narrow saddle. If the delayed ejaculation is situational is is probably psychologic; if it is generalized the problem is probably biologic. Buproprion may be used but it is not all that effective. The patient must be checked to see if there are reversible causes before being given medication. There is research still needed in this area.
The arrival of Pfizer’s blue pill Sildenafil in 1998 brought a great relief both to patient and physician signalling the start of a great era of medical therapy in sexual medicine. Since then the sexual medicine experts have been prescribing sildenafil in erectile dysfunction with acceptable minor adverse events. But the use of sildenafil in premature ejaculation chew sildenafil (PE) is still debated. 2018 being the 20th anniversary of sildenafil, we have compiled interesting facts about the role of sildenafil in PE from various original articles, systematic reviews, meta-analyses, economic brochures and sexual medicine committee guidelines. The major issues in most of these studies were the heterogeneity in the definition of PE and estimating the exact ejaculatory latency time.

After successful intercourse and renewed confidence, men begin to learn the signs of pending ejaculation and ultimately learn to gain increased control. Sex therapy for early ejaculation includes learning a behavioral program designed to improve self-control. In a therapeutic program, the first step is usually education. It is important that the couple have an understanding of the problem, it’s origins, the prognosis and the need to work together toward a satisfying solution. The partner must also understand that the man is not being selfish and that ejaculatory control is unsatisfying for him as well.
The most common behavioral approach taught by sex therapists is either the squeeze technique or an approach described as “start and stop”. These techniques, originally developed by Masters and Johnson, require patience, practice and a commitment to solving the problem. Specific instructions are adapted to the individual and unique characteristics of each patient. With the instructions from the therapist, the patient begins a series of daily masturbatory exercises designed to help him understand his ejaculation pattern and gain control. In summary, under the right circumstances and with ongoing motivation, ejaculation disorders can be overcome.
The most important lesson to be learned by men and their partners is that there is hope and there are therapies that can help resolve the distress of ejaculatory difficulties. Often the first step, deciding to seek treatment and finding the proper professional is the most difficult. The most common sexual dysfunction for men is ejaculatory disorder. These include rapid or premature ejaculation (75%), delayed (8%) often nerve or drug induced, no ejaculation, and retrograde ejaculation from incompetence of bladder neck (ejaculate goes back into bladder instead of out) which occurs after a TURP.
